Answer
$-\frac{1}{8}$
Work Step by Step
$\frac{5}{8} - \frac{3}{4}$ does not equal $\frac{2}{4}$, because to subtract fractions you make sure both have the same denominator and subtract the numerators. For this example:
$\frac{3}{4} = \frac{6}{8}$
$\frac{5}{8} - \frac{6}{8} = \frac{-1}{8} = -\frac{1}{8}$
